Double pre-insulated pipe ECOFLEX Thermo Twin 2x50x4.6/200, 6 bar, temp. 80°C, for central heating and chilled water installations, thermal insulation made of PE-X foam, corrugated HDPE outer jacket /100m/ 1018137

Pre-insulated pipes for efficient heating and cooling installations

Uponor Ecoflex Thermo Twin pipes are a comprehensive solution for central heating and cooling installations, combining the supply and return pipes in a single jacket. Made of cross-linked polyethylene (PE-Xa) with a PE-X foam insulation layer, they provide minimal heat loss and high flexibility, making installation easier even in complex conditions. The corrugated outer jacket made of HDPE protects the pipes from mechanical damage and weather conditions. This is an ideal choice for both professional installers and end customers looking for a reliable and energy-efficient system.

Construction and application

Ecoflex Thermo Twin pipes are characterized by a multi-layer construction designed for durability and efficiency. The inner layer made of PE-Xa ensures resistance to high temperatures (up to 80°C continuous operation, 90°C short-term) and pressure (6 bar). PE-X foam acts as thermal insulation with a thermal conductivity coefficient of 0.04 W/(m.K), minimizing energy losses. The outer jacket made of corrugated HDPE provides mechanical protection and facilitates pipe identification in the installation.

These pipes are widely used in:

• Transport of heating and cooling water in underground networks.
• Central heating installations in residential and commercial buildings.
• Low-temperature systems.
• Biogas plants.
• Cooling networks.

Advantages and benefits

• High energy efficiency: Thanks to the use of PE-X foam with a low thermal conductivity coefficient, the pipes minimize heat loss, reducing the operating costs of the heating system.
• Flexibility and ease of installation: The pipes are easy to bend (minimum bending radius is 1000 mm), which makes it easier to lay them even in tight spaces. They do not require complicated tools or specialized skills during installation.
• Durability and reliability: The materials used (PE-Xa, PE-X, HDPE) are characterized by high resistance to corrosion, aging and mechanical damage, ensuring a long service life of the system.
• Compliance with standards: The pipes meet the requirements of PN-EN 15632 standard and have quality certificates VDI/KIWA, DIN Certco and ATV DVWK-A127 approvals confirming their safety and durability (SLW 60).
• Ready-made solution: Availability of pipes in coils and the possibility of ordering in specific lengths allows for optimal adaptation to the needs of a specific project.
• Self-compensation: PE-X foam compensates for the thermal expansion of the pipes, which increases the stability of the installation.
• Possibility of using Wipex fittings: Uponor Wipex connection technology eliminates the need for welding, speeding up installation and ensuring the tightness of connections.

Ecoflex Thermo Twin pipes are an investment in comfort, energy savings and long-lasting reliability of a heating or cooling system.
